ADJUSTABLE HANDLE.

SPECIFICATION forming part; of Letters Patent No. 384,028, dated June 5, 1888.

Application fi!ed J nne 18, 1887. Serial No. 241.685.

To all whom it may concern.-

Be it known that 1, WILLIAM A. FABER, a citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Adjustable Handles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain i mprove ments in handles, and has for its object to provide means whereby asingle handle may be adjustably attached to various devices, such as brushes, mops, window-washers, handsaws, and the like; and with these ends in view my invention consists in the details of construclion and combination of elements hereinafter fully set forth,and then specificallydesignated by the claim.

In order that those skilled in the art to which my invention appertainsmay understand its construction and operation, I will proceed to describe the same in detail, referring by letter to the accompanying drawings, which form a part of this specification, and in which- Figure 1 shows an ordinary floor-brush provided' with my improved handle; Fig. 2,a similar View of a window-washer. Fig. 3 shows a saw-such as is used for trimming treesprovided with a double-jointed handle in accordance with my improvement; and Fig. 4, a detail sectional view of my improyed handlejoint.

Similar letters denote like parts in all the figures. 4

A is a ball at the end of the shank, which latter is fastened to the brush, washer, saw, or other utensil. This ball is polygonal, for the purpose presently explained. I

B is asplit socket,and O a ferrule extending within thesameandhaving shoulders D,against which said sections rest. Both the sections The ferrule issecured on the end of (N0 model.)

mit the ball, which latter I seat firmly against the annular ring formed by the end of the ferrule. I then adjust the handle to the desired angle and clamp it firmly in this position by are not new; but my invention contemplates the obviation of a great difficulty heretofore existing in the securing of handles adjustably by means of a ball-and-socket joint, and this difficulty is that no matter how much the ball is serrated it cannot be tightly clamped by the socket so as to prevent displacement, whereas in my improvement the polygonal faces of the ball are firmly clamped against the annular seat afforded by the ferrule, so that any turning of the handle is impossible. It has been frequently essayed to attach a handle to a handsaw by means of a ball-andsocket joint; but the difficulty has been that in order to rigidly clamp the saw a rectangular head had to be used, thereby sacrificing the adjustability.

\Vith my improvement the adjustment is universal, while at the same time the saw or other deviceis rigidly held atany desired angle.

Having thus described my invention, I elairn In an adjustable handle, the combination,

with a polygonal-faced ball secured to a brush or other utensil, of a split socket adapted to embrace the ball, a ferrule extending within the socket and affording an annular seat for the ball, and a set-screw extending through the ferruleand the socket and adapted to clamp the latter firmly against the ball,substantially as set forth.

In testimony whereof I affiX my signature in presence of two witnesses.
